在Rust中是否有任何可用的选项来获取特定于平台的文件分隔符？
可以有不同的平台特定分隔符：

let separator = "\\" // Could be this.
let separator2 = "/" // Could be this.
let separator3 = "//" // Could be this.

我看起来像下面的东西：

let env_independent_seperator = env::separator()

那么它可能的用法可以如下：

let folder = "C\\Folder\\Path";
let env_independent_separator = env::separator() // Looking something like this
let file_name = "File.txt";
let full_path = folder+ env_independent_separator + file_name;

Rust里有File::separator()吗？
